My guess is that these are windshield wipers a careful driver had positioned in this fashion because of the incoming snow, (so as not to damage them).
This is assuming there is a car below the snow, of course… 🙂

Sunny , warm (6 degrees Celsius) in Burlington Ontario at 13:50 local time.
Hopefully this will melt the snow presently on the ground.
Unlike most of Eastern north America here at the west end
of Lake Ontario have experienced very little snowfall.
Unlike most of the surrounding geographic areas.
So unlike the the last two winter periods where there
was easily 150 centimetres or more.

Objects in the photo? Thought initially two twigs or similar.

Then again there is that tree to the right and overhead ; thinking maybe
some small bits fell from the above area.

The snow seems to be sticking to whatever is sticking out of the snow
pile which led me to think it was twigs or branches from a form of foliage.
Not knowing what is hiding under the pile of snow makes things difficult
to determine what the marks really are…

I’m going to guess it’s car windshield wipers. All the wipers are up when it snows in Japan…at least in my old village they were..but you could barely see them (like this photo) because if you left your car there for more than a few hours it would be buried. But that’s my guess.
